Definitions
- the invention relates to a method for reducing the volume of materials by pressing in a screw press and a screw press for carrying out this method.
- Screw presses are known in many embodiments. They are used primarily in the plastics processing industry, and they are used to manufacture semi-finished plastic products, but also finished products of various types. It is now known that when processing different plastics, it is necessary to design the screw presses and in particular the screw according to the material to be processed. This leads to a large number of different types of screw presses. The range of screw press manufacturers is correspondingly large.
- Materials are understood to mean free-flowing and free-flowing mixtures of preferably organic substances, waste and mixtures of various types, for example sewage sludge, manure, waste or the like.
- inorganic mixtures e.g. Waste from the chemical industry, understood, which must be processed in such a way that it becomes harmless or can be easily destroyed.
- This object is achieved according to the invention in that the pressing process is carried out in stages, the material being subjected to a throttle treatment after each treatment stage.
- the screw press according to the invention for carrying out the method according to the invention is characterized in that the housing is subdivided into housing elements, between which there is a throttle disk which blocks the free cross section of the screws by forming a passage gap at the core circumference of the screws.
- FIG. 1 is a side view of a screw press according to the "invention
- FIG. 2 is a plan view of the screw press of FIG. 1, partially in section,
- FIGS. 1 and 2 are views of a throttle disk used in the screw press according to FIGS. 1 and 2;
- FIGS. 1 and 2 shows a schematic illustration of the use of the screw press according to FIGS. 1 and 2 when processing a green mass, e.g. Grass.
- the two-screw press shown in FIGS. 1 and 2 has a housing 1, which is composed of housing elements 2, 3, 4, 5, 6, the housing element 2 deviating from the other housing elements 3 - 6 and a loading opening 7 having.
- the housing elements 2 - 6 are connected to one another by screws 8 or screw bolts 9.
- Screw elements 14 are attached to a worm shaft 12, 13, the length of which corresponds to that of the housing elements 2-6. They can be single or multi-course and have the same or a different pitch. The sequence of the screw elements 14 and their number can be adapted to the respective material to be processed.
- a tensioning shaft 15 is screwed in, which extends through the screw elements 14 to the end of the last screw element 'and carries at its end a tensioning flange 16 into which tensioning screws 17 are screwed in are mounted in a clamping head 18 supported in the last screw element 14 and, by turning, enable the clamping shaft 15 and thus the screw elements 14 to be tensioned.
- a throttle disc is arranged between the individual housing elements 3 - 6, the design of which can be seen in FIG. 3.
- the throttle disc 19, with which a narrow gap is formed around the core diameter of the screw elements 14, is composed of two parts 20, 21, which have corresponding bores 22 or slots 23, with the aid of which they are located between the housing elements 3 - 6 are held by the bolts 9.
- the slots 23 in the apex part 21 allow the gap between the throttle disk 19 and the core diameter of the screw elements 14 to be set differently.
- the throttle disk 19 enables the most varied of materials to be processed practically with the same screw press.
- the housing elements 3 - 6, which are, for example, in two parts in FIGS. 1 and 2, and the screw elements 14 need not be changed. An adaptation to different types of materials can be achieved in a simple manner by the housing 1
- the two worm shafts 12, 13 protrude from the housing 1 on the inlet side and extend through a toothed wheel gear and are supported on an axial bearing 24.
- the support can be done in different ways, e.g. through axial rolling bearings. It is essential here that the force exerted by the two worm shafts 12, 13 on the axial bearing 24 is diverted to the housing 1 via tie rods 25 which are fastened in the housing 1, as a result of which a self-contained flow of force is achieved.
- the gear 26, preferably a gear transmission, serves to couple a drive motor and to drive the two worm shafts 12, 13 via the gear 26.
- An expansion pressure sensor 27 is provided between the housing 1 and the gear 26.
- the worm shafts 12, 13 passing through the expansion pressure sensor 27 are supported therein by means of bearings. If spreading forces occur on the worm shafts 12, 13, these are supported via their bearings on the spreading pressure sensor 27.
- the expansion pressure transducer 27 is not supported on the housing 1 or on the gear 26, but is guided loosely on the tie rods 25.
- a shaping or briquetting head 28 is attached to the exit side of the screw press. The material emerging from the screw press can thereby be given a specific shape. Guides 29 serve to discharge the ejected material.
- One or more openings 30 can be arranged in the housing elements 3 - 6 above and / or below. Juice that collects or flows out during the pressing process
- the screw press can be adapted to the respective requirements without significant changes.
- FIG. 4 schematically shows a plant for processing green mass, e.g. Grass, shown.
- the screw shafts 12, 13 of the screw press are driven via the gear 26 by a motor 31 which is coupled to a second motor 32.
- the juice squeezed out of the green mass is drawn in by a peristaltic pump 33 and conveyed into a flocculation container 34.
- the flocculant is added by means of a schematically indicated device 35, the gel which is formed in this case being discharged through a line 36 and the rest of the liquid through a line 37.
- the hose punch 33 can be designed in accordance with the embodiment described in the simultaneously filed patent of the same inventor (CH 3063/82 from May 15, 1982), while the overall system according to FIG .82) works.
- the two further openings 31 serve to extract vapors through a fan 39 or a vacuum pump via a line 38.
- the screw press described thus solves the problem of drying materials on the one hand and simultaneously briquetting on the other hand. Liquids and vapors obtained here can be easily suctioned off and processed separately. It is essential that the press described consists of standardized elements, i.e. can be assembled from the housing elements 2-6 and the screw elements 14, wherein the corresponding number of standardized throttle disks 19 can also be used. It has been with
- OMPI _ Operation of such a press has surprisingly shown that the power consumption of the screw press is relatively low, so that compared to other drying processes there is a lower power requirement, and that a multitude of functions can be solved with the described method and the described screw press.
- the mechanical drying ie without the addition of heat, and the hygienization that can be achieved with it, that is to say extensive sterility and the storage life of the end product that can be achieved thereby.
- the adaptation of the screw press to the different materials to be processed, which vary greatly in composition, is determined by the number and arrangement of the screw elements 14, for example with opposite pitch, and - in the case of two screws 10, 11 - by the operating mode, for example with counter-clockwise or counter-clockwise rotation and with clockwise or counter-clockwise rotation of both screws, achieved quickly and easily.
- the material of the screw elements 14 is expediently resistant to abrasion, for example high-alloy steel, which can also be equipped with hard metal on heavily wearing parts.
